AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Dane,

Do you mind providing some details about the experimental design? How many tasks/conditions? Under what condition/task are you trying to perform the seed-based correlation analysis?

> 3dSynthesize is being used here (with the matrix output from that activation 3dDeconvolve) to help isolate specific conditions of
> interest (by removing the other conditions, motion, and censors) in order to have a cleaner seed signal from which to run an FC
> correlation analysis with the rest of the brain to investigate the network and connections.

If you followed some webpage I created a long time ago, I should probably deactivate/delete it. The 3dSynthesize approach is really a bad idea because it can only remove the average effect across trials, but not trial-to-trial fluctuations.
